Just a quick video of the PULK I built from spare parts.
All in less than $35 spent. Hauls a load well, needs a few modifications but it'll work for me. I'll keep tinkering with it.
I prefer NOT to use rigid tow bars. They are probably fine on the tundra or wide open ground. They DO NOT WORK in the bush that I traverse. Doesn't matter the length, they work great on established trails and wide open spaces, not so much when moving into, around in, and out of heavy timber and brush country.
Contents break down and how to coming soon. So far I am pleased with it.
Music is Ray Wylie Hubbard, the song is A: Enlightenment B: Endarkenment (Hint: There Is No C) from the album by the same name, you can find it here.
